1.Amendment to the Noncompete Agreement. Effective as of the Class C Issue Date, the definition of “Cause” set forth in Section 3(a) of the Noncompete Agreement shall be amended and restated in its entirety to read:

(a)    “Cause” as used in the Charter (as amended by the Governance Amendments) shall mean the occurrence of any of the following (unless otherwise determined by at least 75% of the Independent Directors of the Company): (i) the Stockholder’s material misconduct or neglect in the performance of his duties; (ii) the Stockholder’s failure to devote the time necessary to the performance of his duties as CEO or Approved Executive Officer, as applicable; (iii) the Stockholder’s commission of any felony; offense punishable by imprisonment in a state or federal penitentiary; any offense, civil or criminal, involving material dishonesty, fraud, moral turpitude or immoral conduct; or any crime of sufficient import to potentially discredit or adversely affect the Company’s ability to conduct its business in the normal course; (iv) the Stockholder’s material breach of the Company’s written Code of Conduct, as in effect from time to time; (v) the Stockholder’s commission of any act that results in severe harm to the Company excluding any act taken by the Stockholder in good faith that he reasonably believed was in the best interests of the Company; or (vi) the Stockholder’s material breach of this

Agreement. The Stockholder shall not be deemed terminated for “Cause” as an Approved Executive Officer for purposes of the Charter as amended by the Governance Amendments unless and until a notice of intent to terminate the Stockholder for “Cause,” specifying the particulars of the conduct of the Stockholder forming the basis for such termination, is given to the Stockholder by at least 75% of the Independent Directors and, subsequently, at least 75% of the Independent Directors find, after reasonable notice to the Stockholder (but in no event less than fifteen (15) days prior notice) and an opportunity for the Stockholder and his counsel to be heard by the Board, that termination of the Stockholder for “Cause” is justified, and such termination for “Cause” shall be deemed effective on the date that is five (5) business days after the date that the Board gives to the Stockholder notice of such termination for “Cause,” specifying in detail the particulars of the conduct of the Stockholder found by the Board to justify such termination, is given to the Stockholder by the Board.

2.No Other Amendments. Except as expressly amended as set forth in Section 1 of this Amendment, the Noncompete Agreement shall remain in full force and effect.

3.Miscellaneous. The provisions of Sections 8, 9, 11 through 15, and 18 through 20 of the Noncompete Agreement are incorporated into this Amendment herein by reference, mutatis mutandi.
